Cannot run game with Cesium Google maps

Cesium for Unreal

So when I try to run my scene with Cesium Google Map it show me that error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000250

In viewport it works properly but when I try to run level it immediately quit and give me this error. Does anyone know how to solve it?

Assuming you’re using Cesium for Unreal v1.29.0, this is the line it’s crashing on:

So perhaps you have a sequence actor in your level that somehow doesn’t have a Sequence Player? I’m not really sure why that would happen, but if all else fails you could consider simply removing the sequence actor from the level entirely.

Thank you, how I didn’t notice that, everything works now
